Ellenismo imperiale (hi sec. d.c.)

open access: yesStudia Historica: Historia Antigua, 2010
SOMMARIO: Gli studi di storia del mondo greco nella prima età impériale sono stati particolarmente soltivati in Italia negli ultimi decenni. Si ripercorrono le fasi di questo fenómeno cultúrale, cercando di metterne in evidenza le origini e le ...

Of Truth, Pragmatism, and Sour Grapes: The Second Circuit’s Decision in SEC v. Citigroup Global Markets [PDF]

open access: yes, 2016
In his 2001 letter to Berkshire Hathaway shareholders Warren Buffett stated, “[Y]ou only find out who is swimming naked when the tide goes out.” In the fall of 2008, the tide went out when Lehman Brothers collapsed and credit markets froze.

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

open access: yesFEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Biosynthesis of selenocysteine on its tRNA in eukaryotes.

open access: yesPLoS Biology, 2007
Selenocysteine (Sec) is cotranslationally inserted into protein in response to UGA codons and is the 21st amino acid in the genetic code. However, the means by which Sec is synthesized in eukaryotes is not known.

Laser scribing of silicon wafers [PDF]

open access: yes, 1970
Laser scribing eliminates microcracking at scribe line intersections, minimizes or eliminates preparation of scribe channels, and increases yield during the breaking process. Rapid overlapping of spots in the form of a line permits scribing speeds of 1.5

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

ORGANIZAREA ADMINISTRATIVĂ A EPARHIEI CHIŞINĂULUI ŞI HOTINULUI (sfârşitul sec. al XIX-lea – începutul sec. al XX-lea)

open access: yesStudia Universitatis Moldaviae: Stiinte Umanistice, 2009
The eparchy administration in Bessarabia had a centralized church hierarchy, according to the structure of imperial church hierarchy. Thus, the church administration activity in Bessarabia was being directed by the Holy Synod by means of laws ...

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

XMM-Newton observations of OY Car III: OM light curve modelling, X-ray timing and spectral studies

open access: yes, 2003
We revisit the XMM-Newton observations of the dwarf nova OY Car taken in July 2000 which occured shortly after an outburst. Ramsay et al (2001a) found a prominent energy dependent modulation at a period of 2240 sec: this modulation was only seen for app.
